Kelly Incandela, Gianni's mom, said that a that a woman has been walking around with her son's photo attempting to collect money in his name without her permission.

The stranger, coincidentally walked into Gianni's grandmother's office in Brooklyn asking for a donation on Monday, and was able to walk out of the office free, Incandela said.

"She [the grandmother] confronted the woman, who changed her version three times," Incandela said.

Incandela said they called police, but they told them there was nothing they could do since there was no exchange of money.

"The woman kept saying she wasn't doing anything, but she walked out of the office with my son's picture and a jar full of money," Incandela said.

Incandela said they decided to start a GoFundMe page to collect money for their son's medical expenses last summer and afterward they started receiving emails from the GoFundMe page saying that someone was collecting money for his son's funeral expenses.

Incandela's GoFundMe page raised more than $22,000 since it was founded last summer and it has a goal set for $25,000.

"We feel very fortunate to have you all in our lives and your donations have helped tremendously," a family member wrote on the GoFundMe page.

"Gianni is a very strong little boy," his mom said. "There have been some little complications during the treatments, but his spirit is the same and he remains the little boy of when all of this started."
